Title: Polyphase high-current power supply system - eliminates interference between single-conductor transfers by screens positioned between iron cores and adjacent conductors
Inventor: FREYGANG HANS-JOACHIM DIPL ING
IPC: H02B1/18
Filed: 1978-11-13
Abstract: The power supply system has several adjacent current conductors forming single-conductor transformers with iron iron cores carrying secondary windings. To avoid the adjacent conductors affecting the fault behaviour of the transformers involved, a screen (15-17) is located between the iron cores (6-8) and the adjacent conductors (3-8). The screen is made of ferromagnetic and/or electrically conducting material. The screen prevents the design errors or faults of one transformer being affected by an adjacent transformer. This means that these errors or faults behave in a predetermined way and can be compensated for.

Title: Loudspeaker housing to reduce effect of electrodynamic resonance - has helmholtz aperture tuned to same frequency as resonance peak
Inventor: HENNEL HANS GERHARD
IPC: H04R1/28
Filed: 1979-09-03
Abstract: The tightly sealed casing (1) carrying one or more loudspeakers (4,2,7) has an opening (3) of a variable length or variable dia. By adjusting the combined effect of the cavity volume inside the box (1) and the inertial effect of the aperture (3) it is possible to tune the acoustic system to a frequency equal to the fundamental electroacoustic transducer resonance frequency of the loudspeaker. When then the loudspeaker is mounted into the box, the two resonances interact. Dependent on the coupling factor, spreading of the resonance peak occurs whereby the disturbing single-peak characteristic is avoided and a substantial linearisation of the frequency response is obtained. If the box carries multiple loudspeakers, the medium size speaker must be built into a separate, air tight box (5) having a separate aperture (6). The smallest speaker usually does not require linearisation.
